2CCL562110E1205 ABB - FS401M-B20/0.03

The FS401M-B20/0.03 is a four-pole Residual Current Circuit Breaker with Overcurrent protection (RCBO) from ABB, designed to provide comprehensive protection against electrical faults. This device combines the functionality of a residual current device (RCD) and a miniature circuit breaker (MCB). It offers protection against overload, short circuit, and earth fault currents. The rated current is 20A, and the tripping sensitivity for residual current is 30mA. This ensures rapid disconnection of the circuit in the event of a ground fault, minimizing the risk of electric shock. The 'B' characteristic indicates it is suitable for residential and light commercial applications with moderate inrush currents. It has a rated voltage of 400V AC and is designed for DIN rail mounting, facilitating easy installation in standard distribution boards. The FS401M series is known for its reliability and robust performance, ensuring the safety of electrical installations and connected equipment. This RCBO is ideal for protecting circuits supplying sensitive electronic equipment and areas where human contact with electricity is possible. It helps prevent electrical fires and reduces the risk of injury from electrical faults.
